Volume
The nominal volume of the sprayer tank. Usually, in this case, the working volume is indicated, and not the full capacity (“for the cork”).
The more capacious the sprayer is, the more work can be done with it without refueling. On the other hand, a large volume accordingly affects the price, dimensions, and most importantly, the weight of the unit (and not only in a filled, but also in a “dry” state). Therefore, even with large volumes of work, it is sometimes more rational to use a relatively small unit, refueling it several times.
Detailed recommendations on the optimal volume of the tank for a particular situation can be found in special sources. With regard to specific values, in the most compact manual sprayers (see above), the capacity
does not exceed 2 liters. Tanks for
2.1 – 5 liters can be found both in hand-held devices, and in pump-action and battery models (see "Type") with a shoulder carry. Sprayers for
5.1 – 10 liters are almost all made shoulder-mounted, the capacity of gasoline units actually
starts from 10 liters, and the most capacious modern sprayers have tanks
of more than 15 liters.
Max. spraying distance
The longest distance a sprayer can effectively spray a liquid or powder. Usually, the horizontal range is implied, however, for “long-range” models, values bare also given for vertical spraying — in such units, the difference between horizontal and vertical ranges can be very noticeable.
A “long-range” sprayer (for
10–15 m or
more) is convenient in that it allows you to process a large area without moving, and also to reach high branches without using ladders. On the other hand, a long range requires appropriate power, which affects the price, weight and dimensions of the unit — despite the fact that such capabilities are not always required: for example, for a cramped greenhouse, an atomizer with a short range (
5 – 10 m, and often and
less) So it is worth choosing according to this indicator, taking into account the features of the planned work.
Wand material
The material from which the complete spray tube of the sprayer is made.
— Plastic. The key advantage of plastic over other materials used for spray wands is its low cost. In addition, this material is chemically inert and does not corrode, and also has a low weight. On the other hand, the rigidity of the plastic is not very high, which is why such tubes tend to bend, sometimes even under their own weight.
— Aluminium. Aluminium alloys combine good strength and lightness, such a tube is easy to work with, and it takes quite a strong blow or pressure to bend it. On the other hand, aluminium is expensive.
— Brass. In addition to strength and reliability (including resistance to bending), brass is notable for its excellent resistance to corrosion. The disadvantages of such tubes are the high price, as well as the rather large weight.
- Stainless steel. "Stainless steel" is notable primarily for its high strength and rigidity, which is superior to other materials, despite the fact that this material is relatively inexpensive. However, such tubes weigh much more than aluminium or plastic ones.
- Copper. According to the main operational properties, copper pipes are similar to brass ones: they are strong, reliable and durable. On the other hand, such tubes are relatively expensive and do not have fundamental advantages over the same "stainless steel". Therefore, this option is rarely found.
Wand holder
The presence
of a tube clamp in the design of the sprayer.
Such a latch is a set of special clips, usually installed directly on the tank. It greatly simplifies the storage and transportation of the device: the handset, usually, is placed as compactly as possible and at the same time securely. Yes, and during breaks in work, this feature can come in handy — fixing the tube in the retainer is more convenient and safer than putting it on the ground, holding it in your hands, etc.
